Longi launches a 590 W TOPCon solar panel with an efficiency of 22.8%



There are seven versions of the new series with powers between 560 W and 590 W. The power conversion efficiency varies between 21.7% and 22.8%

According to the manufacturer, the new product is based on TOPCon cells, M10 wafers and high-performance hybrid passivity technology (HPDC).

“The backside of the cell features high and low junctions, optimized membrane design, and advanced deposition techniques to achieve significant full-area passivation with minimal parasitic absorption,” the company explained. “On the front side, the cell is coated with a local low-resistance contact layer that improves cell efficiency. In addition, both the front and rear sides feature improved anti-reflection and low-recombination films and metallization solutions for superior performance.

The dimensions of the new product are 2,278 mm x 1,134 mm x 30 mm and the weight is 31.8 kg. It has 2.0mm double glass, anodized aluminum frame and IP68 rating. The temperature coefficient is -0.28% per C.

There are seven versions of the new series with powers between 560 W and 590 W. The power conversion efficiency varies between 21.7% and 22.8%. The breakdown voltage ranges from 50.89 V to 51.63 V and the short-circuit current ranges from 13.89 A to 14.1 38.

The panels can be used in photovoltaic systems with a maximum voltage of 1,500 V. The company offers a 12-year product warranty and a 30-year power warranty for 88.18% of the initial output.

“Long’s industry-leading product life cycle standards also ensure the reliability of Hi-MO 7. Hi-MO 7 effectively ensures its reliability throughout its life cycle with optimized designs such as high-quality monocrystalline silicon wafers, customized cell paste, optimized module capsule membrane system, SMBB precision joint and highly reliable junction box automatic welding,” stated the manufacturer.

“The application of digitalized manufacturing and quality control platforms, especially intelligent AI detection technology, further guarantees the quality of Hi-MO 7’s products. Therefore, Hi-MO 7 offers a linear power guarantee of up to 0.38%, bringing solid added value to customers. and efficient returns beyond expectations “, it added.
